COLTER.

Application filed January 23, 1926. Serial No. 83,270.

I or lift up the plow because of sticks or wood or stones.

With the ordinary rolling colter and old standing colter, it is practically impossible to do any plowing ins'ticky soil, whereas with my improved colter, the same works efficiently with a minimum amountof trouble regardless as to whether or not the soil is wet or dry.

By the substitution of this improved colter, for the rolling colter on the usual standard of the rolling colter, it is possible to adjust my improved colter, toward or away from the plow as may be desirable.

Another very important obiect ofthe invention is to provide a colter of this nature which is strong and durable, one which is thoroughly reliable, easy to manipulate, and otherwise well adapted to the purpose for whichzit is designed.

With the above and numerous other ob jects in View as will appear as the description proceeds, the invention resides in certain details of construction as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is an elevation of the colter showing the same attached to the colter standard of an ordinary plow beam, and

Fig. 2 is a perspective view of my improved colter.

Referring to the drawing in detail, it will be seen that 5 designates a plow beam having the usual bracket 6 thereon for adjustably receiving the rolling colter standard 7. My improved colter is disposed on the lower end of this standard 7 as is clearly shown in Fig. 1. a

straight edge, a rear str Referring to the cOltersPecifiQaliy. it will be seen that the same includes a blade 8 having an upper edge 9 rectangular-1y disposed to a rear verticaledge 10. A bottom sharpened edge 11 is shorter than the upper edge 9. A front diagonally disposed sharpened edge 12 merges into the bottom edge 11. After the upper portion of the blade'8 there is provided a strap extension which is curved or rolled to form a sleeve 13 which terminates in an extension 14, riveted as at l i 15 to-the blade body 8. The sleeve 13 receives the lower end of the standard 7 held 111 place by washers 16 and pin 17 or in any other suitable manner. l

The colter, therefore, is free to swing laterally by readily freeing itself from sticky soil and from sticks and stones, so as to prevent the raising of the plow when 1n operation. ;It is thought that the con- TOv struction, operation, and. advantages of my 1 invention will now be clearly understood \fv thout a more detailed description thereor.

It is desired, however, to point out that the colter is exceedingly inexpensive to manufacture because of its simple constru'ci tion, and is strong and durable, besides possessing increased efficiency over colters here-, 3

tofore used.

Having thus described my invention, what I claim as new is a A colt-er of thcclass described. designed for use on plows having a colter standard, I

comprising a blade bod;1 having an upper 'ght edge disposed at right angles to the upper straightedge, a bottom straightedge disposed at right in gles to the rear straight edge and sharpened,

and merging into a diagonally extending J forward curved edge which is sharpened,

and a strap merging from the upper for- V ward portion of the blade body and bent to form a sleeve terminating in an extension riveted to the blade body, the upper edge of the strap being co-planer with the upper straight edge. 7

In testnnony whereof I afiix my signature;
